Magnets can be attached or combined together for either increasing or decreasing their strength, depending purely on their orientation towards each other. Integrating the 2 equivalent magnets will not always double their strength, but certainly it will come close.
Integrating the N-to-S
If north side of the one magnet combined with south side of other, so the poles get oriented N-S-N-S, then strength will definitely be close to the double that of the single magnet, on a condition, if they are of the same strength and the shape.
Less Than Double
As the magnets do not take or occupy the very same area so the strength will not be doubled. Although the strengths of the field are additive, field strength on top surface of combined magnet is the range far from other magnet-- namely, width of leading magnet away-- therefore the full result of bottom magnet does not felt.
Combining the N-N
If 2 magnets are integrated and the same poles are facing each other, then their strength of the magnet will be considerably decreased. Strength will not be completely counteracted, as the argument which is specified above that they does not inhabit same area.
Cancellation
Anybody might anticipate that the combined magnets would cancel, such as the electrical charges. However the electromagnetic fields are additive rather.
The Intuition
The magnetism can be viewed as loosely oriented as produced by circles that electrons create in their orbits and if the random orientation of these orbits is occurred they will cancel the each other. But if in the very same direction they all are oriented then the strength of the field is additive and their impact is cumulative.
But do magnets get stronger when combined?
Answer of this concern is here! When you stack the 2 identical long-term magnets then you get roughly strength of the one twice the size. A magnet twice or double the size, then it needs to spread its energy of magnet over two times the volume, hence the strength of the surface of magnet is significantly seldom increased. The smaller neodymium magnets which have the exact same rating normally roughly have the same strength of the surface as the larger ones. It is the holding power that increases, as they have the bigger area.
If you stack or combine the 2 magnets such that the opposite poles are touching each other then they will act like the single magnet of neodymium buy exact same overall height. But if we see technically then this is not true 100%. When you stack the 2 magnets, really you have bit less magnetic product, as a few of the plating layers you have in the middle which you are not having with single magnet. Still this is great approximation- we see hard to measure difference with pull force gauge.
In the today's world, numerous the stacked magnets are being utilized in a lot of the applications and it has terrific usage. Let's see forward in the future what applications of stacked magnet are more to be discovered.
